METTL3 and head and neck squamous cell carcinoma: Moreover, modifying the potential METTL3-catalyzing motif in pri-miR-151 with m6A significantly expedited pri-miR-151 processing to its mature forms(Fig. 5k-m), suggesting that heightened miR-151-5p levels in HNSCC may stem from augmented pri-miR-151 processing by METTL3-induced m6A modification.
